Agrihub INSPIRE Hackathon 2022: Challenge #2 Analytical tools for WhiteBoard

MENTORS: Runar Bergheim, Karel Charvat, Raitis Berzins

Collaborative analysis for smart farming

The MapWhiteboard is used as an add-on to an application that performs automatic zoning of agricultural fields based on remote sensing data. The application takes as input a field, automatically acquires satellite imagery time series data, calculates indices such as the NVDI and uses the resulting 4D data to determine zones in the respective field that should be treated differently with respect to fertilisation, irrigation and pesticide application.

The MapWhiteboard component adds value to this scenario in two ways:

  • Users can indicate points that reside within distinct areas of the field
  • Users can modify the resulting zones after auto-classification
  • Users can add recommendations, rates to the individual zones

Integrated planning tool

The Map Whiteboard is used as a component supporting collaborative planning processes that involve regional sector authorities, local authorities/municipalities and stakeholders in the planning processes from business/industry/real-estate and NGOs/civil society/organisations.

The traditional planning process requires these stakeholders to work together either separately or, traditionally, in meetings. Much of the interaction concerns maps where people with varying experience in interpreting maps and spatial data work together in meeting rooms on big screens or hunched above printed maps laid out on a table.

The MapWhiteboard augments the meeting experience, allows people to see exactly what is referred to and can add contextual information to better understand exact locations. A person inexperienced in GIS concepts can see the map as if it was Google Maps, can switch to satellite/aerial imagery background and make simple annotations. A more technical user may add WMS services and other contextual information. All can see each other’s pointers.

Generic meeting augmentation tool

Inspired by tools like which provides polling functions to ensure participative conferences and which offers a comprehensive digital whiteboard functionality, the MapWhiteboard is in this case used to bring up a map of anywhere on the globe and allow users to cooperate on the surface by drawing and annotating.

After the meeting is ended, the annotations must be saveable, archived for future reference or for export into GIS tools or other visualization solutions.

Agrihub INSPIRE Hackathon 2022: Challenge #4 Climate analysis in the field

MENTORS: Tereza Samanova, Karel Jedlicka, Michal Kepka

In the Autumn AgriHub INSPIRE HACKATHON 2021, the challenge Extreme weather aimed to seek for: 

  • Exploitation of the possible use of Copernicus Emergency Management services including European Flood Awareness System and European Drought Observatory 
  • Integration of the information from volunteer observatories of extreme events repositories to provide additional source of information to be assimilated with traditional observations available or to complement missing observations (e.g., hail) to be used for e.g., insurance claims.
  • Integration of VGIs and citizen science data to validate/assimilate/train remove observations (e.g., crop diseases, grow monitoring)

As a result, the challenge Extreme weather has discovered that, for farmers, it is not their main problem to make practical use of the awareness and observatory systems, but more to have a look at the micro-climatic conditions and specialties in their properties and their specific parts to plan well the crop management and to prevent potential damages caused by extreme weather conditions. Thus the challenge has, based on brainstorming and discussions within the challenge team prepared a draft project called System of smart growth and crop protection reflecting the current micro-climatic development and weather forecasts respecting the individual position of the field.

Processing of sensor data from very detailed sensor network deployed on large field block showed potential of a completely different level of heterogeneity mapping of such field blocks. The problem is to minimize the number of sensors deployed on the field every season to a reasonable amount. When the initial zoning is defined, external data sources can be utilized to model conditions in particular zones of such field blocks based on historical locality conditions and model predictions.

Ambition of the challenge

The concept of the above-described project needs to be validated in multiple locations in CZ and SK, respecting their individual conditions (latitude, altitude, average precipitation, windiness and other indicators of local microclima). Thus, the inclusion of the experimental farms into this challenge is crucial. 

On the other hand, the challenge will be seeking also for the existing examples of good practices already running within experimental smart farming systems and systems of observation and measurements in the fields that deals with weather and climate conditions monitoring. 

  • The aim of this challenge will be, therefore: 
  • Collect the relevant examples from practice
  • Validate the theoretical basis of the System of smart growth and crop protection
  • Develop substance of new product (system) able to enter soon on the market working with observations, measurements, sensors and predictions dealing with weather forecasts and climatic conditions that would help farmers with management of their properties/lands/fields within the principle of smart farming, respecting the climate, weather and specific micro-climatic conditions.

The main ambition of the insitu observations assessment is to define the critical number of sensors for a zoning definition and sustainability of such zoning for further seasons with support of available global data and models. 

Next steps

The challenge continues and more develops the former topic Extreme weather and meets the current needs and requirements of the farmers: they are not keen on macro-data collection but on having access to the history and prediction of the conditions in their individual property. The challenge will collect best practices and data available within similar EU and national projects and forward the technological solution (System of smart growth and crop protection reflecting the current micro-climatic development and weather forecasts respecting the individual position of the field) towards its introduction on the market.

It can help farmers to get very detailed information about the field blocks and improve the variability of interventions planning and applications to minimize expensive inputs.

Agrihub INSPIRE Hackathon 2022: Challenge #6 IoT and EO data integration

MENTORS: Karel Charvát, Michal Kepka

The solution developed under the SmartAgriHubs project in the scope of the Flagship Innovation Experiment FIE20 Groundwater and meteo sensors is an expert system to support farmers in decision-making process and planning process of field interventions. This FIE20 solution integrates various data sources and different analytical processes in a complete system and provides users an easy-to-use web map application as a common user interface. The FIE20 system integrates components developed during the SmartAgriHubs project with results and components developed during previous European research projects – namely FOODIE, DataBio and EUXDAT. The FIE20 solution utilizes components of the SmartAgriHubs Digital Innovation Hub where it is deployed and it uses services from individual DIHs of team members, especially cloud services for data storage and large computations. 

The FIE20 solution integrates different types of data – local sensor data and online analysis based on this data, Earth Observation and remote sensing data, farm and regional thematic spatial data, weather model and forecast data – to be visualized in web application and used in implemented analytical functions. Available analytical functions provide decision-support results oriented on fields status and conditions, support based on long-term data from EO observations, weather models and measurements. 

The web map application provides overview of the locality with visualization of different thematic spatial data on local or regional level, Earth Observation data and various indices. The web map application provides weather forecasts for the locality of the farm and different analyses based on the weather forecast and the forecast model data. Various analytical functions based on spatial and EO data are available in the web map application, these analyses provide information oriented on fields and crops on fields in different stages. Data layers providing – yield productivity zones delimitation from the long time period data, fertilizers variable application maps and NDVI index daily average trend from short time period data represent products of EO data and analytical functions. 

The main agricultural challenges that the FIE20 solution is addressing can be divided in three parts. Firstly, the challenge is to integrate various and heterogeneous data from different sources to one system and to present this integrated data in an usable and understandable form to farmers.  Secondly, utilization of integrated data in combination with external services in a set of analytical functions to provide farmers enough information as a support of decisions. And last but not least, the way how to visualize and present results of analyses to extract information and added values by the most of users of the solution. The solution utilizes a combination of cartographic visualizations, interactive charts and diagrams. 


The software solution developed during the FIE20 experiment utilizes advantages of Digital Innovation Hubs (DIHs) as a web platform for its hosting on one side and data services and functions provided by different DIHs for its analytical functions on the other side. 

The architecture of the FIE20 solution follows the 3-tier architecture design. It has the data access layer represented by the central database and the cloud storage for EO data. The logic layer provides all functionalities of the application and analytical functions. Components of the logic layer of the solution are developed as modular components providing scalability and interoperability of the solution. Presentation layer is represented by a web map application with individual components for visualization of sensor data, analytical functions and layer management. 

The FIE 20 solution uses an open-source component called SensLog as a sensor data management component that integrates data from meteostations, soil sensors and groundwater nodes deployed on fields to own data storage. These sensor data can be integrated from sensors directly or from sensor manufactures’ clouds. The SensLog solution provides integrated sensor data by system of web services to other components of the solution. 

Remote sensing (RS) data are represented by utilization of the Copernicus programme products, namely Sentinel 2 data and different vegetation  indices. These RS data are used mainly as inputs for analytical functions and partly as thematic products for visualization. The FIE20 solution provides analyses based on short-time – represented by the NDVI daily average trend as well as long-time period of RS data – represented by the yield productivity zones delimitation. The analyzes utilizing RS data are implemented using Jupyter Notebook platform and components of the EUXDAT e-Infrastructure. This part of analytical components are easily scalable and modificable due to running on the WirelessInfo Innovation Hub. 

Ambition of the challenge

The innovative aspect of the challenge 6  is mainly represented by integration of various data from different providers in one web map application together with analytical functionalities and tools provided by different platforms and DIHs. Sensor data are downloaded to the central data storage in harmonized data model from different data providers infrastructures and interfaces. These integrated sensor data are provided by a set of web services to other components of the solution or by standardized interface based on the OGC SensorThingsAPI specification to other third parties components. 

Copernicus programme products are utilized for analyses on regional and field level, not only visualization of time-series of vegetation indices are provided, but these EO data are used for analytical functions. On regional level, differences of vegetation indices during the growing season are regularly calculated and visualized in form of charts. Characteristics of fields in the locality from the yield productivity aspect are calculated from the long-term series of satellite data. These characteristics are utilized for calculations of application maps during vegetation seasons. Utilization of weather forecast and weather model data for analytical functions providing predictions is supporting interventions planning on farms. 

The challenge 6 solution will supports sustainability of agriculture by several aspects, but mainly by efficiency of resource consumptions. Utilization of fields characteristics based on long-term EO data provides data source for calculations of variable application maps for application of pesticides and fertilizations. Calculation of yield productivity zones provides input for effective application of fertilizers on additive or compensatory methods. Utilization of short-term EO data in combination with weather forecast provides supporting information for intervention planning in next few days. Available analyses based on weather forecast and weather model data provide important information for planning of optimal time period for field interventions and reducing cases of non-effective utilizations of sources.

Next steps

The next step is to integrate new tools like dashboard and integrate this solution with other Farm Management Systems, integrate functions from other challenges and provided large scale testing.

Agrihub INSPIRE Hackathon 2022: Challenge #3 Food transport monitoring

MENTOR: Jaroslav Šmejkal

The call will cover small food producers operating in a specific region. They also support employment in the region and also promote their uniqueness, for example by selling their specific food products. Sales can be made to locals, tourists, or even in remote regions. For this type of supply chain, it has proved crucial that local food producers are often unable to ensure the consistent quality of food transport conditions from production to the retailer. Local food producers are mostly small producers. Therefore, they do not rely on professional technologies to transport food. The challenge will be to monitor the quality of their products during transport and also to set the appropriate transport conditions. This will also support the quality of local food.

The ideal output of this call would be the design of a set of parameters and their ranges and tolerances, which should ensure the quality of transported products from production to sale. The design should also identify the technologies that can participate in this challenge (sensors, cabling, reliable data transmission, data storage, form of data visualization and archiving, ….). It should be a solution that is technologically simple, cheap, user-friendly, and does not impose extensive vehicle modification requirements.

The solution should be applicable to existing resources. It is a comprehensive approach from the point of view of the manufacturer, transporter, and also the developer of the technology.


Introduction and Context is the support of small regional food producers (regional specialties) who are specific, unique, and give a special spirit to their region. Unfortunately, they are often very small (even seasonal) producers who do not have the financial and technical resources as large and global market players. From this point of view, it is desirable to preserve the spirit of the regions and to support these regional producers.

The ambition of the challenge

The ambition of the challenge is to design a range of parameters that should be monitored during the transport of food from the producer to the seller. Of course, it should also be a matter of determining their values, ranges, and tolerances.

Next steps

  • Design of parameters to be monitored during the transport of regional products from the producer to the seller.
  • Design of a measuring chain for measuring specified parameters.
  • Design of visualization of measured data.

Agrihub INSPIRE Hackathon 2022: Challenge #9 A new social space for geographic information sharing and education

MENTORS: Otakar Čerba, František Zadražil, Marketa Kollerova

We will test a new environment, where the editorial system will be the key unifying element of the geographical data processing. It will enable the creation of a web portal and also provides a natural connection to other parts of the system. The content management system is based on the Wagtail CMS (Content Management System) platform with the CodeRed CMS extension, see and This is one of the leading open source CMS used by small and large organizations (e.g. Google, NASA, British NHS). Wagtail is based on Django and the main development language is Python. It allows easy extension of functionality in the form of widgets, page templates, as well as permissions or other system parameters. It is therefore possible to integrate with others. This CMS is now integrated with tools supporting easy generation of map context.

This shows the connection of powerful Open Source mapping framework HSlayers, which supports visualization of maps.


The content of the challenge will be:

  • to test, how people can develop, publish and share their own maps using Web clients or desktop open source tools
  • to learn how to build nice map composition
  • to build own maps describing specific places or local problems

Ambition of the challenge

  • Support effective reuse of existing data
  • Build new data content
  • Promote regions
  • Prepare new type of educational content

Next steps

Part of planned activities will also be focused on the integration of new tools like IoT tools, dashboards and analytical tools.

Agrihub INSPIRE Hackathon 2022: Challenge #5 Analysis and visualization of sensor measurements

MENTOR: Michal Kepka


Sensor data provides important part of spatial data at all. Especially with spreading of IoT across different domains, huge amount of sensor data can be produced in a short time period. The problem arises with large amount of sensor data collected during observation campaign. The first task is to filter and clean non-valid observations and check periods of data loss or drop-outs. The second task is to prepare initial aggregations of data – hourly/daily/monthly averages, minimums, maximums, sums of selected observed properties. The next step is to prepare analyses based on the target usage of observed data. The last but not the least point is to prepare understandable and usable visualizations of observed and processed data in an explanatory way.

Ambition of the challenge

The challenge should provide extension of the current data flow through the SensLog system and its components to improve the analytical functionality and client-side visualization of observed and analysed data. 

Map window for static sensor nodes

Analytical functions need to reflect current options of data sources – mobile sensors on machinery and delivery pick-ups and large set of static sensor nodes. The set of analytical functions should reflect target domain of the data usage and expected form of analyses. Analytical functions should process collected data as well as integrate data from external sources – remote sensing data, models and simulations. These external datasets can be future observations or predicted values thus the visualization client should be able to distinguish between real and predicted data. 

Visualization of predicted data

Chart visualization for different observed properties of static nodes

Next steps

The challenge will use the SensLog system and its components and data from selected sensor campaigns provided by sensor owners. Challenge task list can be extended by requirements defined by potential end-users of the data flow and client application.

Agrihub INSPIRE Hackathon 2022: Challenge #12 Building a map based social space for Africa

MENTORS: Akaninyene Obot, Marketa Kollerova

During last year’s INSPIRE Hackathon the SmartAfriHubs Digital Innovation Hub ( was developed. Moreover, there was a community built around it, which is now active on WhatsUp and Facebook. We would like this Hackathon to test possibilities of an extended environment, which will be more user friendly and which will allow large active sharing of information by users. It will not be focused only on publishing new maps, but also on developing content in the form of storyboards, producing active content from Africa, using of this content for better training and education, but also supporting sustainable development in Africa. We plan to extend the current community and increase visibility of this solution. There will be all data, which are currently stored on SmartAfriHubs available at the disposal of the hackers, moreover tools for easy data publishing and management, but also tools to develop storyboards and present actively different content connected with map information.

New solution, which is now under development, will be tested with different users. Current platform has architecture according new scheme:

This solution will be available on the Plan4all cloud and will be fully operational.

The basic unifying element of the geodata processing system will be  the editorial system. It will enable the creation of a web portal and also provides a natural signpost to other parts of the system. The content management system will be  based on the CodeRed CMS – (Content Management System). This is one of the leading open source CMS used by small and large organizations (e.g. Google, NASA, British NHS). Wagtail is based on Django and the main development language is Python. It allows easy extension of functionality in the form of widgets, page templates, as well as permissions or other system parameters. It is therefore possible to integrate with other systems used within the organization (city geoportal, etc.) if such a requirement arises in the future.   It is now connected with tools, which are already part of SmartAfriHub. The goal is to help different groups of people to build their own content (maps, text, storyboard and others and share it with the community.

We would like to discuss additional extensions of the system about new functionalities.


The Hackathon will have few steps, which we would like to realize:

  1. Training of participants, how to use single components and how to generate own context and also training about currently available data
  2. Definition of limited numbers of use cases and build a team, who will prepare full context and prepare attractive publication of this context
  3. Implementing of context
  4. Sharing of experiences from use cases and suggestion of improvements
  5. Preparing final presentation and plan for future sustainability

Ambition of the challenge

The main challenges are:

  • to help African students and other people generate own content in attractive from
  • to promote sustainability in African regions
  • to generate new data
  • to provide large scale awareness towards African communities
  • to support future business
  • to prepare scientific publications

Next steps

The main next step is to make new solutions self-sustainable and form a social space, including a broader community, which will help to introduce new technological concepts in Africa, to support capacity building, and generate new data using principles of citizen science.

Another important point is to define future development priorities.

Agrihub INSPIRE Hackathon 2022: Challenge #8 How to use and improve OLU 2.0

MENTORS: Pavel Hájek, Michal Kepka, Dimitrii Kozhukh

Land use and land cover information in combination with other thematic datasets related to detailed reference spatial data in localities forms an important dataset for different analyzes in different domains. Our activity of creating a geographic database OpenLandUse (OLU) aims to be an effective step towards such a model that would effectively gather information about the Earth’s surface in sufficient detail and in sufficiently complex links to be suitable for initiatives such as Green Deal, Destination Earth and the construction of Earth’s twins (Digital Twins).
The OLU 2.0 database combines various thematic data with the most detailed reference geometry available in a given area. Thematic data sets are focused on information on soil cover, soils, topographic or climatic parameters, etc. and in different time periods. The model also supports the possibility of integrating data obtained by evaluating remote sensing data.

Ambition of the challenge

The database covers selected territorial units with a seamless layer, which provides information on various topics on selected reference geometry, which can be a cadastral map, Land Parcel Identification System soil blocks or even elements of the Corine Land Cover data set.

The original purpose of the database was mainly in analyzes for spatial planning and investment, agriculture, landscape development, etc. Our current ambition is to test developed data model and database that support creation of various models of landscape development and scenarios and support the building of large-scale digital models.

The aim of the #8 Challenge is to verify the OLU 2.0 data model is versatile in various areas of human activity, mainly in cooperation with other challenges. Thus we are looking for specialists from various areas of human activity, programmers, remote sensing experts, public administration, land planners, farmers, foresters, nature conservation, real estate experts, business, investments and the like.

Particular goals

  • Enhanced the established OLU 2.0 database with other thematic datasets;
  • Or with the same thematic datasets as already implemented in OLU 2.0, but for different areas of interest;
  • Cooperate with Challenge 5 to be able to incorporate data from sensors into OLU 2.0 as well.

Agrihub INSPIRE Hackathon 2022: Challenge #7 OLU4Africa

MENTOR: Dmitrij Kožuch


The Open Land Use is an initiative of Plan4All association to create seamless land use/ land cover map. At first the initiative was focused on creating OLU map just for Europe filling it just with land use/ land cover data. Later, the extent has changed also to Africa, and the data model has changed to easily integrate other thematic data (soils, geomorphology etc.). 

In the first version of OLU for Africa, just available vector datasets were used: Open Street Map, Africover and some local datasets. The second version used Open Street Map and  S2 prototype land cover 20m map of Africa 2016 from CCI (with pan-African coverage). 

The second version of Open Land Use for Africa was created during Open Spring INSPIRE Hackathon 2021 and the dataset was created mainly based on Open Street Map data and S2 prototype land cover 20m map of Africa 2016 from CCI (Climate Change Initiative).

The goal of the challenge is to improve second version of Open Land Use map for Africa with ESA World Cover data, satellite data and other potential data sources.

The initial attempts were already done. 

The function that uses TerraCatalogue to get World Cover data by given extent is done. Also there has been work done on functions that vectorize data from World Cover, that do computations by tiles (in some large provinces is impossible to do computations without splitting data into data tiles) and than function that merges data tiles.

Some prototype that demonstrates the difference between the second version of OLU for Africa and the new version that incorporates World Cover was created: :

The second version:

The prototype:

As it is seen the advantage of incorporating World Cover is big. Also the incorporation of other data sources including satellite data or some local information, could imporove the result. However, the main goal will be to create the third version of Open Land Use for Africa, that will incorporate World Cover, and the addition of other data sources will be features that are good to have.

Ambition of the challenge

In this challenge the main focus will be to create the third version that will incorporate World Cover dataset by ESA. Additionally, the revision of new suitable data sources will be done.

Next steps

The description of World Cover dataset is given here: .

The programming language that is used is Python 3, and the outcome data is stored in PostgreSQL database. The code for creating of the second version of OLU for Africa is available: 

The prototype code to be used for creation of the third version will be shared soon.
